Pruning, reshaping and yield-increasing method of kiwi fruit in mountain land

Abstract

The invention provides a pruning, reshaping and yield-increasing method of kiwi fruit in a mountain land. The method comprises the following steps: shearing the tip of the main stem of the kiwi fruit so that two buds at the upper end are cultured to form main branches and tendrils which respectively grow along the two sides of a shed frame; shearing and removing unnecessary main branches and tendrils and binding the branches and tendrils in parallel at the end of the year; in the second year, leaving axillary buds at the even number positions of the main branches and tendrils to be used as fruiting mother branches in the same year, and eliminating the axillary buds at the odd number positions of the main branches and tendrils to be used as the fruiting mother branches in the next year; and after fruiting on the fruiting mother branches and harvesting, pruning the fruiting mother branches in the end of the same year so that new buds can grow in the next year and become growing branches, in such a way, alternatively culturing and pruning the axillary buds at the even and odd number positions and the fruiting mother branches, and culturing and pruning repeatedly and circularly annually. The method provided by the invention has the beneficial effects that unnecessary branches are sheared and removed annually and abstemiously according to different positions and a planned way, the unnecessary axillary buds are eliminated, fruiting branches after harvesting are sheared and removed, the fruiting mother branches and the growing branches alternatively develop and mature annually, and nutrition substances in soil are concentrated to mainly be supplied to fruits, so that the yield per mu is improved.

Description

technical field [0001] The invention relates to a method for cultivating kiwifruit, in particular to a method for pruning, shaping and increasing yield of mountain kiwifruit. Background technique [0002] Kiwi fruit is a kind of vine fruit, which has a long history of cultivation in my country. It is generally distributed in the warm zone of 23°-34° north latitude and the northern subtropical mountains; its fruit is rich in nutrients, with a total sugar content of 8%-14%, mainly glucose, The second is fructose, which has a higher acidity, with a total acidity of 1.2%-2.0%. In addition, it also contains 12 kinds of amino acids, rich in protein, calcium, phosphorus, potassium, iron and other minerals, and is one of the most nutritious fruits; It is comprehensive and rich, and contains some important substances that are indispensable to the human body. Therefore, it plays an important role in maintaining human health, preventing and curing diseases. Eating more kiwi fruit can pr...

Problems solved by technology

When the lateral branch grows beyond the outermost end of the beam, short cutting and thinning are used when the distance from the ground is 50-60 cm, and long, medium and short branches are combined for pruning; for pruning of elongated branches, generally 5-6 short buds are left. Cut off to make 2-3 branches germinate; for the long fruiting branches, generally cut and leave 3-4 buds on the fruiting part of the previous year; cut and leave 2-3 buds for long fruiting branches and middle fruiting branches; this method There are many disadvantages. The main reason is that the potential of kiwi fruit cannot be increased. Secondly, the elongated branches still exist, which consumes nutrients, and the ventilation and lighting are very poor, which seriously affects the weight and quality of kiwi fruit.
